A: A horizontal cabling extends directly from the horizontal cross-connect in the telecommunication room to the workstations.
A backbone cabling connects the telecommunications room with outside services, or connects telecommunications rooms together, or between buildings.

A: Structured cabling is a building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements called subsystems. These subsystems are the Work Area, Horizontal Cabling, Telecommunications Room, Backbone Cabling (Riser), Equipment Room, and Entrance Facility. A structure cabling can have a cabling infrastructure based on optical fiber, copper or a combination of both media.

A: The Return Loss is the loss of signal power resulting from the reflection caused at a discontinuity in an optical fiber. This discontinuity can be a mismatch with the terminating load or with a device inserted in the line. It expressed in decibels (dB).

A: Keystone is the term use to define the standard rectangular profile in connectors and jacks, patch panels, faceplates, surface mount boxes and other outlets that connect different part of a network together. They are interchangeable between different Keystone product manufacturers.

A: T568A and T568B are both wiring schemes used today for terminating pairs in networks. It is important to ensure that the workstation connectors and patch panels are wired to the same pattern. There is no difference in performance between the two standards as long as the same scheme is used across the cabling system. T568A wiring scheme is widely used in Canada in contrast with the USA where the T568B is favored.

A: The Wirewerks CAT5e modular connectors are capable to run up to 350MHz even through there is no standard requiring to run at that level. Nor is there any performance requirements established at that frequency.

A:USOC’s expanded acronym is Universal Service Ordering Code. This an old Bell system identifying a particular service or equipment offered under tariff. USOC specifies the order in which wires are connected in a 4, 6, 8 position modular connector/jack.

A: Keywerks patch panels are a series of independent Keystone jack/connectors each to be terminated individually.
Wirewerks 110-Type patch panels present modular blocks of 6 unified jacks with 110-type termination block at their rear.
